Traditional mitigation strategies, such as radiation-hardened components and shielding, offer partial protection but incur significant mass and efficiency penalties and do not address transient plasma-induced disturbances. This study presents a physics-informed, plasma-resilient design methodology for DC–DC converters in deep-space applications. A comprehensive space-environment simulation framework is developed to model heliocentric plasma density, solar wind velocity, proton energy spectra, and surface charging, incorporating both low- and high-frequency fluctuations. Building on this, a radiation-aware, adaptive DC–DC converter topology is proposed, coupled with a model reference adaptive control (MRAC) architecture and disturbance observer, enabling real-time mitigation of plasma-induced voltage fluctuations, SEU step events, and input ripple. Simulation results demonstrate that the proposed approach maintains the output voltage close to the nominal value under the considered space-environment disturbances. The adaptive controller reduces the RMS voltage error from approximately 10.3–12.6 V in the uncontrolled system to approximately 1.86–1.91 V across the investigated operating scenarios while significantly suppressing transient deviations caused by plasma fluctuations and SEU events. Frequency-domain analysis confirms effective attenuation of low-frequency plasma-induced transients, while Lyapunov-based stability proofs ensure guaranteed closed-loop robustness. The integrated methodology enables reliable, efficient, and adaptive energy management for long-duration space missions, highlighting the importance of environment-aware hardware-control co-design for future deep-space spacecraft. © 2026 Informa UK Limited, trading as Taylor & Francis Group.Taylor and Francis Ltd.2026Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/10168https://doi.org/10.1080/10420150.2026.27215151042-0150enRadiation Effects and Defects in Solidsinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/10168
